Dog Swim Day: For the annual day of pups in the pool on Saturday, St. Petersburg Recreation Department offers two sessions to let man's best friend paddle around Fossil Park Pool and even leap off the diving boards. The first session is 9:30-11 a.m. and the second is 11:30 a.m.-1 p.m. for leash-free swim and play for pups before the pool closes for the season. Register at either start time with proof of dog's current vaccination. But sorry, kids, no swimming for humans. $5 per session for dogs, humans free. Fossil Park Pool, 6739 Dr. Martin Luther King Jr. St. N, St. Petersburg. (727) 893-7732.

Concert

Brad Paisley, Def Leppard: The country star and '80s rockers have played the MidFlorida Credit Union Amphitheatre regularly and this week we get a double dose of musical comfort food for the dog days of summer. With both acts, the template is set in stone: Guitars, guitars and more guitars, all backing hit after hit. But comfort and familiarity are powerful emotions. That's the real reason thousands of fans will flood the Amp to see Paisley perform at 7:30 p.m. Friday ($15 and up) and Def Leppard at 7 p.m. Monday ($18 and up). 4802 U.S. 301 N, Tampa. (813) 740-2446. livenation.com.

Comedy

David Liebe Hart: The off-kilter alternative comic, musician and puppeteer is best known for his appearances on Adult Swim's Tim and Eric Awesome Show Great Job! He scored some cult hits (Father & Son, Salame) from his bizarre catalog of songs about aliens, religion and failed relationships and he has an assortment of eclectic puppets and tells oddly endearing stories of paranormal encounters. New World Brewery, 1313 E Eighth Ave. in Ybor City at 8:30 p.m. Saturday. $10. ticketfly.com.

Star gazing

Perseid meteor shower viewing: Skywatchers' summertime favorite, the Perseid meteor shower, returns this week, and this year astronomers expect an outburst of 100 to 200 meteors per hour — about double the usual rate. Peak times are from 11 p.m. to 4:30 a.m. today and Friday, according to Earthsky.org. But you need to find a dark enough place to appreciate it late into the night. Luckily, the very-dark Dade Battlefield Historic State Park in Bushnell is opening its gates 8-10 p.m. Friday to invite visitors to take a night walk along trails before stopping to view shooting stars. Entry is $3 per vehicle, $2 for those walking or on bicycles. The park is at 7200 County Road 603, Bushnell. (352) 793-4781.

Snake charmer

Alice Cooper: The iconic rocker takes the stage in Clearwater Saturday. Well known for his penchant for snakes on stage, he still has that sense of serpentine showmanship that has worked wonders for the 68-year-old Rock and Roll Hall of Famer. He may not have a snake on his shoulders when he hits Ruth Eckerd Hall on Saturday, but he'll bring nearly 50 years of carnival-barking experience, along with a stable of iconic hits like I'm Eighteen, School's Out, Poison and Elected. And that still works wonders, even for his younger fans. 8 p.m. Saturday, 1111 N McMullen-Booth Road, Clearwater. $48.75 and up. (727) 791-7400. rutheckerdhall.com.

Kink club

The 16th annual trade show brings vendors, models and a Super Heroine Showdown (1 p.m. Saturday). New this year, the Twisted Dungeon play space is open to everyone 18 or older attending the convention. $40 per day, $107 all-access, $25 after-party. It opens at 7 p.m. Thursday and runs from noon to the wee hours Friday through Sunday with lots of parties planned. 333 First St. S, St. Petersburg. fetishcon.com.
